hi, i recently sat for a 3unit maths exam where there were two questions one was written down worng and the other was a four unit integral. I answered the 4unit integral correctly and spent like 10mins on the error question. during the exam students told the teachers that they looked like errors yet the teacher said it was right. they took out these questions which i spent 20mins all up and i didnt get any marks where even others didnt bother answering them. I presented my case to the maths coordinator and then the principal and they said they can do nothing. should i go to the board of studies to appeal for the marks i deserve, any suggestions
